Another 68mm Billet VTG Build -- GT2 !!
Yes I have!


It is Q-U-I-C-K! It will blow your mind.I've owned quick cars, my Z06 had 900HP and 800FT# with MT's and it hooked pretty well when careful - this just takes off like a rocket.I do have a V-Box I will time it and you can time yours. what do you want...0-60, 60-130, and 0-100?

When we did the 788 # on our 6 speed car, it was on C16 and 25psi....so slightly higher boost then we normally run. Sorry, I corrected my original post. But, on the standard pump file, the 6 speed car made 725 awhp. Basically, the tiptronic costs you about 35-40 hp at the wheels unfortunately.
That is correct.

Thanks Tom.....I am learning. I want to know what a built engine will handle relative to PSI/Bars and thus WHP and Torque given the drive trane (including the other upgrade we have been talking about) is built to withstand the forces of the maximum potential of the 68mm VTG.
We can talk about that Monday or feel free to give me a call/e-mail at any time.
Hopefully I will see the car tommorrow and I can put a few hundred miles on it. Please call me to arrange the "drop off" point.

Now go enjoy your family...I've had enough of mine!!
I presume that was the standard pump file with standard (91-93octane) pump gas, right? Damn, that's impressive if that's the case.
edit: are you referring to the 997tt or the GT2tt here?

No, we swapped intake manifolds to the standard 997 Turbo ones. They're significantly better then the stock GT2 manifolds when you're trying to make big power.
That was 93 octane on the standard pump file...23psi, but keep in mind, that was our 6 speed 997TT car. The tiptronic cars put down less.
LOL..I've had enough too!! I'm on my way to airport right now heading back to FL...tethering my laptop to my phone and checking 6Speed!
All of the actual dyno graphs in this thread are from a GT2.
That 725awhp number I mentioned was our 997TT 6 speed car.
Sorry for the confusion....

This is CMS's thread to post their build on a customer's car. If you have questions, I'm sure Tom and the car's owner will try and answer. If you simply want to disrupt this thread, find a different venue to vent.

post #101 contains the Mustang Dyno 4WD graphs.
Boost is indicated in the graphs also
Thanks Louis. That is quite a bit of boost to be running out of that size compressor. Considering the way the torque falls off, have you looked into running a higher flowing exhaust housing? Have you seen any repeatability issues due to heat soaked components and high EGT's?
